Abstract

The invention discloses a semi-trailer integrated transfer device for a guy-rope-free petroleum drilling machine and a workover rig. The device realizes semi-trailer integrated transportation of the guy-rope-free petroleum drilling machine and the workover rig by adopting a mode that a semi-trailer with high carrying capacity is adopted to replace a self-propelled workover rig carrying vehicle and a guy-rope-free derrick is adopted to replace a mast-shaped guy-rope derrick. Meanwhile, the defects of a mast-shaped guy rope derrick of the workover rig are overcome, and the performance is improved. The invention further provides a transferring and installing method of the device. The conversion process among the drill floor surface low-position working condition, the drill floor surface high-position working condition and the semi-trailer integrated transferring working condition can be achieved, and the conversion sequence is from the transferring working condition to the low-position working condition to the high-position working condition to the low-position working condition to the transferring working condition.

Description

technical field [0001] The technical field of the oil drilling rig and the workover rig of the present invention relates to a semi-trailer integrated transporting non-guyline oil drilling rig and workover rig device. Background technique [0002] The conventional self-propelled workover rig is equipped with a mast-shaped derrick. This derrick needs to be equipped with a plurality of guylines, especially the multiple guylines on the upper section of the derrick must also be dug on the well site and buried anchors for pulling the guylines. In addition, when the conventional self-propelled workover rig is moved between wellheads, the supporting base of the workover rig needs to be disassembled and transported to the new well site for reinstallation. [0003] The above-mentioned conventional self-propelled workover rig and its transportation and installation methods between well sites have the following disadvantages: [0004] The dismantling and transportation of the workover ...
